ABSTRACT:
A housing having an interior chamber with an inlet and outlet thereto is suspended by a crane within a ladle or furnace having an interior refractory surface to be relined. A feed conduit for conveying dry refractory material entrained in an air stream extends through the inlet into the interior chamber. A nozzle assembly having a pair of oppositely positioned spray nozzles is rotatably supported in the outlet of the housing. A conduit of the nozzle assembly is rotatably connected at one end by a coupling to the feed conduit within the housing and communicates with the spray nozzles. Each of the spray nozzles includes a water ring that receives a wetting agent, such as water, from a supply conduit that is connected by a swivel assembly to the nozzles to permit rotation of the nozzles relative to the supply conduit. Each water ring directs the water into mixture with the air entrained dry refractory material flowing through the nozzle. A reversible, variable speed motor is drivingly connected to the nozzle conduit within the housing and is remotely controlled to oscillate the nozzle assembly at a preselected rate through an arc of a preselected angle to apply the refractory material to a worn quadrant of the interior surface.
